HIGHLIGHTS:
· 4 weeks of an 8-10 week reconnaissance geological mapping and rockchip sampling programme has been completed
· A total of 70 rockchip samples have been collected to date and submitted to the laboratory for analysis, with 3 assay results returned to date
· Initial analysis, geological mapping and rock chip sampling has highlighted:
o Somero Project has prospective pegmatites up to 1,200m long and 50m wide with an initial rockchip assay of 4% lithium oxide ('Li2O')
o Erajarvi Project has prospective pegmatites up to 800m long and 30m wide with an initial rockchip assay of 1.29% Li2O
· Key lithium minerals petalite, spodumene and lepidolite were all identified in hand specimens
· The remaining assays are expected to be received over the next four to six weeks and the results will be announced as soon as practicable thereafter
· Finland is one of the most prospective countries on mainland Europe for potential lithium discoveries. Both project areas have excellent access to high quality infrastructure and are located close to potential final customers
David Archer, Savannah's Chief Executive Officer said today, "We are very pleased that this early work is already confirming both encouraging grades and defining significant pegmatites at surface containing key lithium minerals. Finland is a lithium focus for a number of companies, both because of its excellent mining legislation and its infrastructure endowment. These initial results are promising and we keenly await the next set of results."

SOMERO LITHIUM PROJECT
Savannah's Somero Reservation (Figure 2) is located less than 2km south of TSX listed Nortec Minerals' Kietyonmaki and Hirvikalio lithium deposits, which were drilled by the GTK (Finnish Government Department). Historical geological mapping of the area has confirmed the presence of 56 pegmatites, some with the lithium minerals petalite and spodumene, but no geochemical sampling had been completed to date. Recent work completed by Savannah focusing on these pegmatites has highlighted a series of pegmatites up to 1.2km in length and 50m wide, with some of the pegmatites like the Torkkomaki prospect containing massive zones of petalite, which has returned a high-grade lithium assay result of 4% Li2O (Figure 3). A total of 70 rock chip samples were collected and submitted for analysis and to date three assays have been returned.

ERAJARVI LITHIUM PROJECT
The Erajarvi Project (Figure 4) reservation covers a swarm of at least 61 known pegmatites that have been mapped in the area, but to date no geochemical sampling has been conducted. Preliminary mapping indicates that the potential lithium bearing pegmatites are in the contacts of the granite plutons or in the schists close to the contacts, with larger pegmatites over 10m wide generally not encountered farther than 1.5km from the granites.
The larger pegmatites in the region include Niemelä pegmatite, which is up to 30m wide and at least 800m long) and Vitaniemi, which is at least 400m in strike, over 100m in width, 10m in thickness and open in all directions. The prospectivity of these pegmatites was confirmed in the recent mapping and sampling program with abundant lithium minerals spodumene, lepidolite, petalite identified in the Vitaniemi pegmatite and a sample collected from here assaying 1.29%Li2O (Figure 5).
Further detailed mapping and systematic sampling of the Erajarvi reservation is now underway, with this work expected to take at least four weeks.

Notes
Savannah Resources Plc (AIM: SAV) is a growth oriented, multi-commodity, development company:
Oman
Savannah has interests in three copper blocks in the highly prospective Semail Ophiolite Belt in Oman. The projects, which have an Indicated and Inferred Mineral Resource of 1.7Mt at a grade of 2.2% copper and high grade intercepts of up to 56.35m at a grade of 6.21% Cu, with additional gold upside potential, provide Savannah with an excellent opportunity to potentially evolve into a mid-tier copper and gold producer in a relatively short time frame. Together with its Omani partners, Savannah aims to outline further mineral resources to provide the critical mass for a central operating plant to develop the deposits, and in December 2015 outlined exploration targets of between 10,700,000 and 29,250,000 tonnes grading between 1.4% and 2.4% copper.
Mozambique
Savannah has agreed to acquire 100% of Matilda Minerals Limitada which currently operates the Jangamo exploration project, and has agreed with Rio Tinto to form a joint venture in Mozambique to develop the combined Mutamba/Jangamo Project. Formation of the joint venture remains subject to approval by the Ministry of Mineral Resources and Energy of the Republic of Mozambique. Jangamo has a 65Mt Inferred Mineral Resource at a grade of 4.2% total heavy minerals ("THM") at a 2.5% cut-off grade. The Mutamba, Dongane and Chilubane deposits have a combined exploration target of 7-12Bn tonnes at a grade of 3-4.5% THM (published in 2008).
Finland
Savannah has registered applications over two new lithium projects, Somero and Erajarvi, covering an area of 159km² in Finland. Savannah holds a 100% interest in these projects through its Finnish subsidiary Finkallio Oy. Geological mapping by the Finnish Government within the project areas has highlighted the presence of lithium minerals spodumene, lepidolite and petalite with the Government also identifying Somero and Erajarvi as one of the most prospective areas to discover lithium deposits in Finland. Savannah plans to initiate an exploration programme including data compilation, geological mapping and surface sampling with the aim of generating drill ready targets during 2016.

Criteria |
JORC Code explanation |
Commentary |
|
Sampling techniques |
· Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. · Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. · Aspects of the determination of mineralisation that are Material to the Public Report. · In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
· Assay results obtained relate to rock chip sampling · All rock chip samples were random in nature to ensure that they were representative · Total sample of around 1kg was pulverized for assaying · Samples were geologically logged on site and there AMG co-ordinates recorded. · Samples are then dispatched to ALS Laboratories in Perth for analysis using the following process route. · Whole sample is dried at 85°C, Crush to 70% -10 mesh (2mm), 100% pulverize to 85%passing -200 mesh (75 μm). · Al2O3, As, CaO, Co, Cr2O3, Cu, Fe2O3, K2O, Li2O, MgO, MnO, Ni, Pb, S, SiO2, TiO2, Zn all assayed via inductively Coupled Plasma - Atomic Emission Spectroscopy (ICP - AES). A prepared sample (0.2g) is added to sodium peroxide flux (~2.6g), mixed well and then fused in a 670°C furnace. The resulting melt is cooled and then dissolved in 30% hydrochloric acid. This solution is then analysed by ICP-AES and the results are corrected for spectral inter-element interferences. · Cs, Nb, Rb, Sn, Ta, Th, U all assayed via inductively Coupled Plasma - Mass Spectroscopy (ICP - MS). A prepared sample (0.2g) is added to sodium peroxide flux (~2.6g), mixed well and then fused in a 670°C furnace. The resulting melt is cooled and then dissolved in 30% hydrochloric acid. This solution is then analysed by ICP-MS and the results are corrected for inter-element interferences.

· The analytical techniques used are appropriate for the elements and mineralization styles being explored for. · Savannahs QAQC protocol is to industry standards with standard reference material and blanks submitted at a minimum of 5% frequency rate. |
|
Verification of sampling and assaying |
· The verification of significant intersections by either independent or alternative company personnel. · The use of twinned holes. · Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. · Discuss any adjustment to assay data. |
· No independent or alternative verification of the assays has been made · No adjustments have been made to the assay data |
|
Location of data points |

· Holes have been located using a handheld GPS unit using WGS84 · No topographic data is available |
|
Data spacing and distribution |
· Data spacing for reporting of Exploration Results. · Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. · Whether sample compositing has been applied. |
· Sample spacing was random and based on geological observations · Samples were collected along or on potential mineralized rock types |
|
Orientation of data in relation to geological structure |
· Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. · If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
· Sampling has predominantly targeted pegmatite bodies and at times the alteration halo around the pegmatites into the country rock |
|
Sample security |
· The measures taken to ensure sample security. |
· Chain of custody is managed by Savannah. Samples are stored on site in a locked yard. Samples are then transported to Perth by airfreight. Savannah personnel have no contact with the samples once they have been dispatched. |
